</p> <p> 電流互感器原理 [2] 是依據(jù)電磁感應(yīng)原理的。電流互感器是由閉合的鐵心和繞組組成。它的一次繞組匝數(shù)很少，串在需要測(cè)量的電流的線路中，因此它經(jīng)常有線路的全部電流流過(guò)，二次繞組匝數(shù)比較多，串接在測(cè)量?jī)x表和保護(hù)回路中，電流互感器在工作時(shí)，它的二次回路始終是閉合的，因此測(cè)量?jī)x表和保護(hù)回路串聯(lián)線圈的阻抗很小，電流互感器的工作狀態(tài)接近短路。 </p> <p> 在發(fā)電、變電、輸電、配電和用電的線路中電流大小懸殊，從幾安到幾萬(wàn)安都有。為便于測(cè)量、保護(hù)和控制需要轉(zhuǎn)換為比較統(tǒng)一的電流，另外線路上的電壓一般都比較高如直接測(cè)量是非常危險(xiǎn)的。電流互感器就起到電流變換和電氣隔離作用 [1] 。對(duì)于指針式的電流表，電流互感器的二次電流大多數(shù)是安培級(jí)的（如5A等）。對(duì)于數(shù)字化儀表，采樣的信號(hào)一般為毫安級(jí)（0-5V、4-20mA等）。微型電流互感器二次電流為毫安級(jí)，主要起大互感器與采樣之間的橋梁作用。微型電流互感器也有人稱之為“儀用電流互感器”。（“儀用電流互感器”有一層含義是在實(shí)驗(yàn)室使用的多電流比精密電流互感器，一般用于擴(kuò)大儀表量程。）上海喆和定制銷售西門子APT（原上海二工）ALH-0.66
